The specific embodiment
Referring to figs. 1 through Fig. 3, label 10 and 12 refers to the upper mold section and the female die of hot-moulded device respectively.These two half modules 10,12 have the forming surface 14,16 of oneself respectively, and they are on the position respect to one another, along with move to the matched moulds position from die sinking position, plastic plate L are applied predetermined moulding pressure.
Figure 1 shows that when plastic plate L hot-moulded process finishes two half modules are in the situation of matched moulds position.Plastic plate L at first is heated to plasticization temperature and is between two half modules 10,11 of die sinking position.May have a packaged decorations thin plate R and be arranged between two half modules together with plastic plate L, this packaged decorations thin plate R will be fitted on the surface of plastic plate L during plastic plate L hot- moulded.Half module 10,12 is equipped with cooling system usually, and this is the plasticization temperature that is cooled to be significantly less than thermoplastic for the temperature of guaranteeing plastic plate L during hot-moulded.
One of two half modules (being female die 12 in the example of being introduced) are provided with at least one injection molding seat 18, and it communicates with injection road 20.18 designs of injection molding seat are used for forming plug-in unit 22, and for example, it has shape shown in Figure 4.Plug-in unit 22 shown in Figure 4 is just as an example, and it comprises a part 24 that has hole 26, and the center line in hole is orthogonal with plastic plate L basically.Part 24 is connected with plastic plate L by three wallboards 28 that are fixed on the plastic plate L, and edge 30 separately, every wallboard edge connects.
Figure 1 shows that the structure of hot-moulded equipment, its residing state is to have finished and before plastic material is injected injection molding seat 18 in the hot-moulded operation.Injection molding seat 18 is limited between the part and slide block 32 of half module 12, and slide block 32 half module 12 relatively slides, and makes plug-in unit 22 demouldings that form in injection molding seat 18.Slide block 32 has the surface 34 of a hot-moulded molded surface part that constitutes half module 12.
